IceWM is a window manager that controls the appearance, placement & manipulation of windows. The goal of IceWM is speed, simplicity, and not getting in the user's way. It is a light window manager which should be familar to Windows users. IceWM seems to work well in Puppy, and plays well with Rox-filer. Its appearance can be changed by using different themes.

The default window manager in Puppy is JWM but you can replace it with IceWM if you want.

There is a thread in the Puppy forum where users are posting IceWM themes to modify the appearance of IceWM in their Puppy. You can try these themes too once you have IceWM installed.
